Gibraltar have sacked head coach Allen Bula ahead of their European Championship qualifying visit to Scotland on 29 March.
The 50-year-old had been in charge for the first four games of Gibraltar's maiden campaign, losing them all.
The Gibraltar FA said the decision was a result of a "thorough and careful investigation into internal matters".
"The search for a new Gibraltar national team manager will begin immediately," added its statement.
"The Gibraltar FA has come to the decision that an immediate change was appropriate.
"It is not a decision that has been reached lightly or hastily.
"The Gibraltar FA is committed to safeguarding football on the Rock and ensuring that the national team remains the pinnacle of Gibraltarian football."
Bula, who played at semi-professional level in his Gibraltar homeland, had been coach since 2009 and was assisted by a Scotsman, David Wilson, a former junior player with Kilwinning Rangers.
The British Overseas Territory, which lies off the south coast of Spain, made their first senior international appearance with a friendly against Slovakia in November 2013.
Gibraltar drew that match and, in their subsequent four friendlies, they lost to Faroe Islands, lost and drew with Estonia before beating Malta 1-0 in June.
However, they lie bottom of Group D after conceding 21 goals and scoring none in their four qualifiers - losing 7-0 to both Poland and Republic of Ireland, 3-0 to Georgia and 4-0 to world champions Germany.
They next face Scotland at Hampden Park.
Bula's departure comes a few weeks after Desmond Reoch stepped down as GFA president.
